Choosing Internal vs external Clock
I do a project with the newer STM32 G , C series and i am curious what are the benefits of external clock vs using the internal clock, because it will save cost and layout space ?

Hello, as in this post i'm linkingIs there a way to use absolute encoders/resolvers ... - STMicroelectronics Communityi need to use a Biss-c absoulte encoder for a servo drive application using BLDC motors with STSPIN32G4, we are testing using EVSPIN...
Resolved! Changing the pin connections on the STM32F407VET6
Hi.I have Uart pins (Rx/Tx) PA3 and PA2 on STM32F407VET6. Can these pins be changed to I2C (SDA SCL) in the program?Are the pins on STM32 that have been assigned a protocol (SPI/I2C/Uart) constant and cannot be changed or replaced?Thank you.
STM32F413VGT datasheet: inconsistent I2C rise/fall times
The maximum I2C (Standard) Rise Time/Fall Time of STM32F413VGT is stated as 0.1us/0.3us, but STM32 Datasheet says 1us/3us. Please confirm which one is correct.
STM32F407 Option Byte 0xFF, bricked chip
Hi fellows,I have a custom board with STM32F407VGT6. The board was able to be programmed via the JTAG (4 wire JTAG interface; Boot pin is pulled low to ground and reset is connected to the JTAG interface (Nrset pin)) with a segger programmer - multip...
LPTIMER Counter for Delay in STOP2 mode not working
Hello,I have application which go to STOP2 mode once no LPUART/Modbus communication (Running at 32Khz LSI clock) is in progress.Using lptimer for silence timeout logic for UART data frame completion. The code sometimes cause delay during modbus commu...
Resolved! DMA to SPI triggered by Timer STM32H723
Hi All,I am trying to send data to SPI1 via DMA1 Stream 0, using a timer to trigger DMA.Currently, I have used TIM4 Channel2 and Enabled DMA Update with DIER register (UDE bit).DMAMUX1 Channel 0 Request is set to 32.So far, this part seems to work: I...
Resolved! ReadMemory Uart STM32F4xx
Hello, i am stuck on UART topic and i have an argument with someone.He states that ReadMemory(0x11) is sent by STM32. Is that really so? Does STM32 at any point sends "0x11" as response? I must be missing something...
stm32h7: Do the separate IWDGs reset separate cores, or both cores?
Hi in an dual core stm32h7, if we use each iwdg for each cores, when iwdg trigger reset,it will reset the particular core or both the cores will reset.If particular core reset happens means, how to manage the other core from initial boot.Suppose if c...
